NITED STATES PATENT QFFICEQ THEODORE HINRIOHS, OF BALTIMORE, MARYLAND.

ADVERTISING MEDIUM.

SPECIFICATION forming part of Letters Patent No. 364,588, dated June 7, 1887.

Application filed Man 11 16, 1887. Serial No. 231,126. (No model.)

timore city, State of Maryland, have invented certain new and useful Improvements in Advertising Mediums, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 represents an exterior elevation of my improvement, showing a portion of the perforated tube- 4 frame adapted to support the various parts of my device. These sections are made of any suitable material-such as spun n1etal--and may be of any appropriate design and configuration and ornamented or embellished in any suitable manner to constitute an attractive medium for displaying the occupation or profession of the owner.

The lower section, A, is provided with a weighted base, a, to give a firm support to the device and to obviate the danger of the same toppling over, and the upper section is designed to have its top surmounted by a suitable ornament, the said ornament having a tube or passage, I), through which the heated air passes from the interior of the frame, as I will hereinafter indicate.

Each of the sections A and B is provided with a plate or diaphragm, O and D, respectively, and the lower section, A, has a second plate, E, which is located below and contiguous to the plate 0, as shown in Fig. 1, these plates 0, D, and E being held together and uniting the sections by suitable tie-rods, c, and securing-nuts d. The plates 0 and D are per- Fig. 2 is a plan of one of the forated with an annular or other series of openings e, (see Fig. 2,) through which pass the ends of suitable transparent tubes, F, of colored glass or containing colored liquids. The

lower closed ends of said tubes pass through the perforations in the plate 0 and rest upon the contiguous plate, E, while their upper ends, which are open, extend slightly above the plate D, and receive rubber or otherstop pers, which preventsthe evaporation of the liquids within the tubes. perforations e the plates are provided with openings 0, which not only lessen the weight of said plates, but also furnish means for the escape of heated air within the frame.

The tubes F, as before stated, may be constructed of any transparent material, although I prefer to use'glass, and may be of round, square, octagonal, or other form, and so mounte d between the plates that they may be readily removed in case of breakage or when it may be desired to modify or change the existing combinations of colors to vary the effect.

Through the center of the lower section, A, passes a gas-pip'e, g, which may be attached to the supply-pipe leading from themain, and on top of said pipe 9 is screwed or fitted a In addition to the Fig. 1.

By experimenting with several forms of burners I have found that a burner having a small round opening, at, is best adapted for lighting up the space between the annular series of tubes, as it produces a thin elongated flame, which illuminates the tubes and produces abeautiful effect, the flame being protected by ashade or chimney, which conducts the heated air to the passage or tube b in the upper section, B, from whence it escapes into the room.

It is obvious that instead of using gas as the illuminating agent I may employ an electric light or a common oil-lamp, the resultin either case being the same.

The upper section, B, of the frame is preferably divided at a, so that the upper portion becomes a cover, which is removable to facilitatethe filling or the insertion and removal of the tubes and for lighting the centrallydisposed burner.

In operating my device, the coveris removed IOC and the tubes filled with. the colored liquids, (care being taken to leave a small space between the liquid and stopper to accommodate the expansion of the former,) the gas is lighted and the cover replaced.

I am thus enabled to provide a comparatively inexpensive and compact device and one which is especially attractive, as thelight reflected through the colored tubes produces many varied and beautiful effects.

In connection with the frame and differentcolored tubes I employ a motor, M, of any approved construction, and connect the same by gearing with the lower plate, E, in such manner that a rotary movement is imparted to the plates, thereby beautifying the effect of the transparent tubes and presenting to the eye an ever changing combination of brilliant colors.

Small anti-friction rollers r are let into the bottom of the plate E, and bear upon a contiguous flange or track, thereby reducing the friction caused by the rotary movement of the plate.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-=- 1. An' improved show-globe for drugg sts, comprising an upper and lower sectlon united together, and each having a perforated plate,a series of closed glass tubes passing through said plate, a second plate carried by the lower section and mounted on a suitable track, anda motor in the lower section connected with sald plate and rotating the series of tubes and plates, substantially as described.

2. The section A, having the perforated plate 0, the plate E, arranged contiguous thereto and supported on an annular track, and an upper divided section having a perforated plate, D, and passage or tube 1), 1n combination with a series of transparent liquid-con taining tubes passing through said perforated plates and provided with elastic stoppers, tie rods, and securing-nuts for uniting the sections, and a light within the center of the frame and the series of tubes, substantially as herein described.
